Abstract
The invention relates to the technical field of agriculture irrigation, and particularly discloses a low-voltage self-cleaning net-type continuous filter. At present, filters for cleaning filter screens mainly comprise a back washing type filter and a self-cleaning type filter according to an agriculture irrigation technology, wherein the back washing type filter requires the high water pressure in a back washing process, the cost and the energy consumption are greatly improved, and a cleaning effect is not ideal; and according to the other self cleaning type filter, two phases, namely, a filtering stage and a cleaning stage, are needed in work, the disadvantage of the short work cycle is caused, and the cleaning efficiency is low. The low-voltage self-cleaning net-type continuous filter provided by the invention comprises a shell, wherein the shell is provided with a water inlet and a water outlet, an inner cavity of the shell is provided with a barrel-shaped filter screen and is driven by a driving device; the barrel-shaped filter screen is assembled with an end cover through a ball bearing, the inner side of the end cover is fixedly provided with two upper baffle plates, and a position of the lower part of the inner cavity of the shell, corresponding to the upper baffle plates, is fixedly provided with two lower baffle plates which are same as the two baffle plates; and the lower baffle plates are provided with brush bodies, the brush bodies cling to the surface of the filter screen, and gaps are arranged between the edges of the baffle plates and the inner cavity of the shell.
Description
Technical field
The present invention relates to agricultural irrigation technology, specifically a kind of low pressure self-cleaning net formula continuous filter.
Background technology
At present, in agricultural irrigation technology, the filter of filter screen capable of washing mainly contains two types, and one is back flush type; Another kind is auto-flushing net formula.
The operation principle of back flush type filter realizes by changing the direction of a stream of water clearing up impurity residual on filter screen, although this backwashing manner can realize the self-cleaning to filter screen, but effect is bad, a lot of intractable impurity still can remain on filter screen, affects filter effect.In addition, the hydraulic pressure that backwashed range request is higher, substantially increases cost and energy consumption.Affect filter effect.This is a kind of working method of interval simultaneously.
At present, auto-flushing well strainer is all cleaned by brush and filter screen friction when cleaning filter screen, but needs to be divided into two stages during work, i.e. filtration stage and wash phase is a kind of working method of interval equally, and the filtration work period shortens.Except above shortcoming, in brush brush filter screen process, due to hydraulic pressure effect, cleaning performance also and bad.
Summary of the invention
The object of the invention is to want to provide a kind of low pressure self-cleaning net formula continuous filter, to overcome the defect that prior art exists, realize uninterrupted filtration and self-cleaning.
Technical scheme of the present invention comprises housing; Be made up of mix tank, overhead gage, lower baffle plate, brush body of barrel strainer, power transmission shaft, bearing, storage; Shell one end top is provided with water inlet, and rear end cap is provided with delivery port; Be provided with impurity discharging port below housing, the opening part of impurity discharging port is provided with the assorted tank of storage, and the assorted tank of storage is provided with sewage draining exit; Power transmission shaft is contained in housing forward end by bearing and covers, and power transmission shaft is equipped with barrel strainer, and power transmission shaft is connected with the motor be fixed on support arm; Assembled by ball bearing between barrel strainer and barrel strainer end cap, two pieces of overhead gages are fixed with on inside barrel strainer end cap, the bottom of housing cavity and overhead gage opposite position are fixed with two pieces of lower baffle plates, and lower baffle plate is equipped with brush body, and brush body and screen surface are close to; Gap is provided with between the edge of baffle plate and housing cavity.
Further, the cross section between two pieces of described overhead gages is fan-shaped.
Advantage of the present invention is that structure is simple, and cost is lower, is in the region that pressure is less bottom barrel strainer, is conducive to brush body cleaning impurity, the pressure reduction of filter intake-outlet and the pressure reduction of filter intake-outlet of the prior art less; Cleaning performance is good, and cost is low, convenient later maintenance, has the advantages that to realize continuous filtration and cleaning.
Accompanying drawing explanation
Fig. 1 is external structure schematic diagram of the present invention;
Fig. 2 is the axial sectional view of Fig. 1;
Fig. 3 is that the A-A of Fig. 1 is to sectional view.
Detailed description of the invention
In figure: 1 delivery port, 2. rear end cap, 3. drive end bearing bracket, 4. water inlet, 5. power transmission shaft, 6. bearing, 7. housing, 8. storage assorted tank, 9. barrel strainer, 10. overhead gage, 11. lower baffle plates, 12. brush bodies, 13. barrel strainer end caps.
From Fig. 1, Fig. 2, Fig. 3, comprise housing; Be made up of barrel strainer 9, power transmission shaft 5, bearing 6, the assorted tank 8 of storage, overhead gage 10, lower baffle plate 11, brush body 12; Shell one end top is provided with water inlet 4, and rear end cap 2 is provided with delivery port 1; Be provided with impurity discharging port below housing 7, the opening part of impurity discharging port is provided with the assorted tank 8 of storage, and the assorted tank 8 of storage is provided with sewage draining exit; Power transmission shaft 5 is contained on housing forward end lid 3 by bearing 6, power transmission shaft 5 is equipped with barrel strainer 9, and power transmission shaft 5 is connected with the motor be fixed on support arm; Assembled by ball bearing between barrel strainer 9 and barrel strainer end cap 13, two pieces of overhead gages 10 are fixed with on inside barrel strainer end cap 13, cross section between two pieces of overhead gages 10 is fan-shaped, the bottom of housing cavity and overhead gage 10 opposite position are fixed with two pieces of lower baffle plates 11, lower baffle plate 11 is equipped with brush body 12, brush body 12 and screen surface are close to; Gap is provided with between the edge of baffle plate and housing cavity; The bottom of barrel strainer 9 is in the less region of pressure.
When the present invention works, when certain some of barrel strainer is positioned at housing bottom, brush body all once cleans the filter screen at this position, and because the pressure in this region is less, water velocity geo-stationary, the brush body 12 on baffle plate easily can clean filter screen.Cleaned by brush body the impurity discharging port of impurity below housing got off to enter in the assorted tank 8 of storage, and released by the sewage draining exit on the assorted tank 8 of storage.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to technical scheme of the present invention the apparent change of extending out or variation be still in the row of protection scope of the present invention.
